Icahn then repeatedly asked Wapner if he had been to bachelor parties and heard language similar to Trump's. Wapner, shaking his head, eventually said, "I have not heard that kind of language."

"Well then you don't go to bachelor parties or you're a hypocrite," Icahn responded.

In defending the comments, Icahn said that if we held all politicians to the same standard, then more than 90% of the people in Congress would not be there.

"He didn't know that was going to be televised or on a radio program or would even be taped," Icahn said. "It's one thing to do it in a locker room. ... You're going to tell me that anybody who said anything bad about a woman — not bad, but joking — about a woman in a locker room ... then I don't think you'd have anybody in Congress."

Icahn also noted that former presidents John F. Kennedy and Bill Clinton had extramarital affairs.

"To say that that doesn't happen — and with the highs, the most mighty, it happens — and then make this the reason you don't elect a guy, I think, is hypocritical," said Icahn.

"How about Kennedy? How about Clinton for Christ's sake? How about most of our presidents? Kennedy used to have girlfriends over there. We're being hypocritical."

Wapner wrapped up the line of questioning by asking if Icahn still thought Trump could win. The hedge fund legend said he did, but that Trump's chances were "not as good" as they were before the tape was leaked.
